well as the heat of-the condensed moisture.

A. plamt which may be used for carrying the invention into effect is diagrammatically illustrated in the accompanying drawing. In the illustrated example the impure water or other liquid is supplied at the top of the tower A and descends in stages in counter current to air which is moved by means of the blower C. The air. takes up heat and is conveyed through pipes c to the bottom of the tower B in which it meets with a counter current of pure water or other liquid). From the top of the tower the air which has been cooled and substantially freed from yapour is conveyed to the fan C to repeat its cycle of operations. Impure water is discharged at a, and pure water at 12,,

The described method of transmitting heat by means of a circulating current 'of air involves no losses of heat from the air. By means of a finely divided spray the temperature of the hot water can be actually brought down to the temperature of the incoming cold water so that it is possible to attain a very high degree of efliciency. Claims: f '1. An apparatus for transmitting heat from one body of liquid to another, com-' prising means for causing a relatively cold gas to pass in direct. contact with a counter current of hot liquid, and means to cause the gas so heated to pass in direct contact wit a counter current of cold liquid. a current of air or other gas, which efl'ie'cts 2. An apparatus {for transmitting heat aeration of the impure liquid having an from one body of liquid to another, comprisoppbsite direction of flow. The gas takes'up ing means for maintaining a closed circuit heat partly by becoming heated itself and of heat interchanging gas, and means to artly in the form of vapour, in that it will heat said gas in one portion of its circuit by passing the gas in direct contact with a counter current/of hot liquid, and means 9 to abstract heat from said gas in another ortion of its circuit by subsequently passmg the heated gas in'directcontact with a counter current ofliquid to be'heated.

3. An ap aratus for transmitting heat 95 from one body of liquidtoanother body of liquid by means of a current-of gas, comprising two chambers, means for introducing a ray of hot liquid throu h the top of one amber, means for intr 'ucing a spray of 109 Be it known that I, EINAR MORTERUD, a sub e ct of the King of Norway, residing at Chr1stiania, Norway, have invented certam new and useful Improvements in Apparatus for'Transmitting Heat from One Liquid to Another; and I do hereby declare the following .to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification. I

It frequently occurs that'an impure liquid which has been used or treated for some purpose is dischaged in a hot condition at thesame time as it is desired to have a pure li uid heated.

t is well known to transmit the heat from an escaping liquid to a fresh quantity of liquid through a wall according to the counter current principle.

Such an arrangement however involves an expensive" apparatus if it is desired to transmit a considerable percentage of heat. If the temperature 'diife'rences' are quite small large heating surfaces "must be employed. In addition a deposit will after sometime be formed upon the heating surfaces. According to the present invention 'an improved result is attained by the use of moisture. Finally the gas will attain the temperature of the ingoing liquid and be saturated with moisture when it has passed through a sufliciently finely divided spray of theliquid, and when in another ap aratus for example a tower at the bottom 0 which it is introduced it meets with a similar finely divided ray of water or other liquid to be heated, owing in an op osite direction from the to of the tower- 1t will gradually become 00' ed giving ofi its owr'r heat as c cold liquid through the top of the other In testimony that I claim the foregoingv as my Invention, I have signed my name in presfirce of two subscribing Witnesses.
